Like snoopy said in another post... I haven't seen many .ws names sell. Though, I think this name has alot of potential.
The biggest problem is that .ws names don't come close to having the perceived value of a dot-com, dot-net, dot-org, or even a dot-info or dot-biz domain name.
I think you could sell this pretty easily to a freebie site. Although, a problem with freebie sites is that most of the people visiting there don't have much expendable income.
$50-$100, maybe.
